In recent years， the world has suffered many major power safety incidents caused by extreme weather events that have severely impacted economic and social development and global energy transition. Considering the development strategy of China’s new power system and the realistic problem of frequent extreme weather events and climate risks， we analyzed the correlation between the new power system and climate， and expound the broad connotation of "adaptability" based on the concepts of "resilience"， "flexibility"， "reliability"， and "stability" to describe the level of power system safety. We thus established a framework for analyzing the climate adaptability of the new power system and explored the key issues and strategies for enhancing the climate adaptability of the new power system. Furthermore， we delved into the research direction of high-quality development of the new power system from the perspective of climate risk adaptability to enrich the theoretical study of the new power system within the framework of a climate-resilient society.

To promote the adoption of wind power and carbon emission reduction for an electric-thermal integrated energy system， this study proposes a low-carbon economic dispatch model and a solution method for the electric-thermal integrated energy system， considering combined cycle gas-steam units， power to hydrogen and heat， compressed air energy storage （CCGT-P2HH-CAES）， and demand response. First， a collaborative operation framework for the CCGT-P2HH-CAES was constructed to fully utilize the charging and discharging potential of CAES and recycled thermal energy of P2HH. Second， a two-stage low-carbon economic dispatch model for an electric-thermal integrated energy system was established. In the first stage， an economic dispatch model was proposed for an electric-heat integrated energy system incorporating CCGT-P2HH-CAES. The carbon emission responsibilities of the demand side were quantified using carbon emission flow theory. The second stage adopted the bilateral Shapley value method to calculate the carbon emissions range on the demand side. It was then optimized to minimize the difference between the carbon emission responsibility costs and demand response benefits. Finally， a solution procedure for the two-stage model was designed. The improved 6-bus power system and 6-node thermal system were investigated in several case studies. The results show that the proposed model and method can achieve economic operation， wind power utilization， and carbon emission reduction in an electric-thermal integrated energy system.

Extreme ice disasters can cause frequent blackouts and shutdowns. Flexible Emergency Resources （FERs） play a complementary role. Coordinating multiple FERs to participate in scheduling facilitates system recovery. This study proposes an integrated energy system operation framework that considers FER coordination during ice disasters. In the pre-disaster prevention stage， a robust optimization model is constructed to solve the FER pre-scheduling scheme. In the post-disaster resistance and recovery phases， a two-layer optimization model of an integrated energy system considering the FER is established. Emergency repair of the upper line and load reduction of the lower node are transmitted in real-time to realize rapid emergency repair. Simultaneously， the system scheduling is optimized by the mobile energy storage team to reduce the comprehensive load reduction rate of the system and improve flexibility. The case study shows that the proposed framework can effectively reduce the comprehensive load reduction rate by 32.16 % and improve the ability of the system to resist disasters.

With the large-scale development of distributed generation （DG）， flexible control of power flow in a distribution network can be realized using a soft open point （SOP）， which further enhances the ability of a flexible distribution network （FDN） to adjust the power flow. In this study， a low-carbon planning model of an FDN based on an improved carbon emission flow theory is established. First， the carbon emission characteristics of the FDN are analyzed and an improved method for carbon emission flow calculation for the FDN is proposed. Considering the characteristics of DG and SOP， a low-carbon planning model of the FDN is established based on the improved carbon emission flow theory. Furthermore， based on second-order cone programming， the proposed model is solved to obtain an optimal low-carbon planning scheme for the FDN， and the carbon flow distribution of the entire network is obtained by combining the carbon emission flow theory. Finally， the proposed model is analyzed and verified using an improved IEEE 33 node distribution system. The results indicate that reasonable coordinated planning of DG and SOP can effectively improve the economy of system operation and reduce carbon emissions.
